 override System::Security::Cryptography::RSAParameters ExportParameters(bool includePrivateParameters);

public override System.Security.Cryptography.RSAParameters ExportParameters (bool includePrivateParameters);

override this.ExportParameters : bool -> System.Security.Cryptography.RSAParameters

Public Overrides Function ExportParameters (includePrivateParameters As Boolean) As RSAParameters

パラメーター

includePrivateParameters

Boolean

プライベート パラメーターを含める場合は true。それ以外の場合は false。

戻り値

RSAParameters

RSA のパラメーター。

例外

CryptographicException

キーをエクスポートすることはできません。

例

次のコード例では、これを使用して作成されたキー情報を RSACryptoServiceProvider オブジェクトに RSAParameters エクスポートします。

try
{
   //Create a new RSACryptoServiceProvider Object*.
   RSACryptoServiceProvider^ RSA = gcnew RSACryptoServiceProvider;
   
   //Export the key information to an RSAParameters object.
   //Pass false to export the public key information or pass
   //true to export public and private key information.
   RSAParameters RSAParams = RSA->ExportParameters( false );
}
catch ( CryptographicException^ e ) 
{
   //Catch this exception in case the encryption did
   //not succeed.
   Console::WriteLine( e->Message );
}

try
{
    //Create a new RSACryptoServiceProvider object.
    using (RSACryptoServiceProvider RSA = new RSACryptoServiceProvider())
    {

        //Export the key information to an RSAParameters object.
        //Pass false to export the public key information or pass
        //true to export public and private key information.
        RSAParameters RSAParams = RSA.ExportParameters(false);
    }
}
catch (CryptographicException e)
{
    //Catch this exception in case the encryption did
    //not succeed.
    Console.WriteLine(e.Message);
}

Try

    'Create a new RSACryptoServiceProvider object. 
    Dim RSA As New RSACryptoServiceProvider()

    'Export the key information to an RSAParameters object.
    'Pass false to export the public key information or pass
    'true to export public and private key information.
    Dim RSAParams As RSAParameters = RSA.ExportParameters(False)


Catch e As CryptographicException
    'Catch this exception in case the encryption did
    'not succeed.
    Console.WriteLine(e.Message)
End Try
